Synthesis and performance of Li3(V1−xMgx)2(PO4)3 cathode materials

Li3V2(PO4)3@C/graphene composite with improved cycling performance as cathode material for lithium-ion batteries

“…This problem can be partly solved by metal doping [20][21][22] or mixing with electronically conductive materials such as carbon [23,24]. Compared to traditional carbon, graphene nanosheet (GNS) shows excellent electronic conductivity and has been demonstrated as truly effective conductive additive for LIBs [25,26].…”

The Electrochemical Performance of Li3V2(PO4)3/Graphene Nano-powder Composites as Cathode Material for Li-ion Batteries

“…However, despite of these advantages, the intrinsic low electronic conductivity of about 2.3 × 10 −8 Scm −1 at room temperature, which is major drawback for the application of the LIBs, limits its rate capability [6,10]. In order to improve the low electronic conductivity, many efforts such as minimizing the particle size, doping with metal or surface coating with conducting materials were conducted [11][12][13][14][15][16][17][18][19][20][21][22]. Although the carbon coating is generally employed as a useful method towards improving the electronic conductivity of the LVP, it is difficult to cover uniformly the carbon on the surface of the LVP particles.…”

Li3MxV2−x(PO4)3/C (M=Fe, Co) composite cathodes with extended solubility limit and improved electrochemical behavior

“…7 Among the reported dopants such as divalent Co 2+ and Mg 2+ , [8][9][10] combustion method with a novel fuel, viz., oxalic dihydrazide (ODH) has been chosen to prepare Li 3 M x V 22x (PO 4 ) 3 /C cathodes, which is the highlight of the study. ODH, a fuel with a fuel calorific value (FCV = 10) greater than those of conventionally used fuels, such as urea (FCV = 6) and glycine (FCV = 9), 19,20 decomposes at a temperature as low as 250 uC and aids the process of combustion of the selected precursor.…”
